not enough fuel and tons of n2o = boom!!!!!

 

plus it advances the timing causing predetonation, which will crack a piston or bend a rod in a hurry!

 

ha, i said something like that. er not.

 

1st things first, I'm not picking on anyone, I just picked this one to quote.

Okay the reason Nitrous oxide is considered Forced Induction is that it is forcing additional oxygen into the combustion chamber. It's the introduction of more oxygen than would normally be pulled into the motor that makes it forced induction. Technically a ram air scoop is forced induction, it's just speed dependant and not easily measured and regulated.

Turbochargers and superchargers compress the ambient atmosphere thereby forcing more oxygen into the engine. Nitrous oxide skips the compression wheel and adds "pre-compressed" oxygen into the chamber. Everyone makes a big deal over which one is better when they all do basically the same thing but by a different path.
Supercharger is driven by the crank, turbo by the exhaust, N2O by externally compressed gas. Forcing additional oxygen (so you can burn more fuel) to get a bigger explosion inside the combustion chamber is the ultimate result of all 3 methods.
If you want a modification that benefits both n/a and N2O, go for the port and polish manifold or one of the soon to be available headers. They'll both improve your power on and off the juice without the chance of accidently leaving the piggy on when you wanted it off, or having the wrong map loaded on track day!

There's my 2 cents worth, I hope it answers some questions.

 

yeah, because gasoline is soooooo natural right? and gee, what is n20 mixing with, oh thats right GASOLINE!

and since we're breaking down initials lets look at the other letter. A, thats right boys and girl the very first letter of the alphabet, and what does it stand for?
as·pi·rate
tr.v. as·pi·rat·ed, as·pi·rat·ing, as·pi·rates
3. To remove (liquids or gases) by means of a suction device.

gee, now last time i checked, N20 is a f***ing gas

the natural part stands for air that is not only natural, but also NOT i repeat NOT being forced in by another bi-product

THEREFORE using N20 in addition to your engine in a way is like using a more potent gas, so, those of you who say your engine isnt N/A when using N20 are WRONG sorry, i know its tricky and confusing a lot of you and your going to try and come up with some theory of magical proportions to say im wrong, but try using logistics

 

Gasoline is the fuel. However the fuel gets into the engine is a moot point. N/A or FI refers to how the air gets in.

Gee, last time I checked, it was compressed enough to become liquid, which would mean it is not sucked out of the bottle by the engine's vacuum, but sprayed into the intake under pressure.

Not forced in by something like 1200psi of pressure in a bottle in the trunk, perhaps?

 

thank you for explaining that cause alot of people dont know but you explained it better than me. I thought FI is self explanatory, Nitrous, FI come on. but you had to break it down piece by piece. hope everyone understands

 

Just say your "juiced" or on the "sqeeze"... then we all just get along right? This point isn't worth arguing as everyone has different opinions.

 

Nitrouos oxide is certainly forced in, air however is not. NA, (to me) simply means that air is sucked in to the motor at NORMAL ATMOSPHERIC PRESSURE. Burning Nos does not raise atmospheric pressure, does it? THIS IS THE ONLY REASON I REFER TO IT AS N/A. Turbo chargers and Superchargers are all guaged by the amount of pressure they produce over atmospheric pressure, Nos isn't, as well all know. Can we all agree that perhaps it doesn't fit into either category perfectly? Because we are all saying nearly the same thing, then just putting it into the opposite category. If we continue this, I think it's a good idea to start hearing other peoples' definitions of F/I and N/A. Mine is up above, and I think it supports my logic (flawed or no).

May be a bad example, but I see it kinda like putting gasoline in the fire vs pointing a box fan at it.


*ALSO* LETS NOT ALL TALK DOWN ON EACH OTHER. THIS TOPIC IS A LEGITIMATE DEBATE, RESPECT. Thanks to all who are participating.

 

I agree w/ the legitimate debate Booze! However, If atmospheric pressure were to be measured by the amount of oxygen per cubic centimeter (what most combustion chambers are measured in) then yes, N2O increases the atmospheric pressure. I agree that the explanation is tricky but the end result is still the same. Artificially introducing additional oxygen and fuel by an external source as described above equals forced induction.

On a side note for those asleep in science class... Everything in this world (and outside for that matter) will be in 1 of 3 states at any given time. Q: What determines the state of an object? A: The temperature it's currently at. Remember that mercury is a metal that's liquid at "room temperature". Temperature and pressure dictate what state something is in, every state is relative to external conditions. That N2O is liquid in the tank not due to temp but due to the pressure being applied. Think of the CO2 in a bottle of soda, the gas is compressed and rises when you open the top. It will continue to do that untill the pressure is equalized inside and out... becoming "flat".

 

Tsk tsk, there's 5 states of matter, not 3. Solid, liquid, gas, plasma, and bose-einstein. Back to the topic.

 

well all i can say is that where i come from a nitrous car can not enter a na race. it is considered a form of fi. and n2o also changes compression because when the oxygen molecules break free from the nitrogen, the nitrogen doesnt compress the same. raises compression. so yes internal combustion pressures are raised, even thought the manifold is not pressurized. n2o is a form of fi. check all the recordbooks. any record held by a car that is equiped with n2o is filed under the fi catigory. only all motor cars are under the na catagory.

 

Cool right on guys thanks for the explanations.

 

Doh!!!!!


I didn't want to get post detonation with plasma and BEC is only been proven for a few years now... I'll go sit in the corner w/ the pointy hat now sir!

 

True, even if the N2O system wasn't used. Its mere presence disqualifies a car from the N/A category.
